How to Play Marked For Mayhem

Four rival Operators enter shared missions against enemies, challenges and bosses, but each earns individual medals and only one finishes first. Choose a weapon, develop its abilities during the run, and decide when helping defeat a common threat matters more than disrupting a rival. After a match, drone modifications can strengthen later battles. That tension between a shared mission and a personal win is the basic way to understand play.

The Mission: Shared Encounters, Personal Medals

The four Operators face common enemies and bosses, alongside arena games, mindspace challenges and traversal time trials. These activities award medals, which change each player's position on the leaderboard. You therefore need to get through the mission's obstacles, but merely being on the same team against an enemy does not make victory shared. Your own medal total is what puts you ahead of the other Operators.

This is the first relationship to keep in mind: fighting a common threat can help you continue through an encounter, while the challenge or boss still creates a chance to improve your personal standing. Watch both parts of the mission rather than assuming every cooperative action has the same competitive payoff.

Weapon Choice and the Build You Make During a Run

You choose a weapon at the start of a mission. During that run, you can purchase abilities and modifiers and combine found items into build synergies. Your starting choice gives you something to develop, while later choices shape how you tackle enemies, challenges and rivals in that particular run. The official description does not prescribe one beginner weapon or one best combination, so the useful first choice is to learn what your selected weapon does and look for upgrades that work with it.

The weapon build belongs to the current run. It is different from the drone modifications made between matches. Keeping those two layers separate makes the game's progression clearer: make the best of the options presented during this mission, then consider longer-term improvements after it.

Cooperation and Sabotage

The other Operators face the same mission threats, yet they are also competing with you for medals and first place. Marked For Mayhem explicitly allows interference: Disruptors can damage rivals, and boss abilities can be redirected toward them. The choice is not simply “cooperate” or “fight players.” It is when to focus on the shared encounter and when an opportunity to disrupt a rival could improve your own position.

An Operator can gain an edge without having the highest-damage build. That makes timing and the situation around an encounter relevant to your choice of abilities and interference. You do not need to assume that every moment should be spent attacking rivals; the shared enemies and challenges still have to be dealt with for the mission to move forward.

Between-Match Drone Modifications

After a match, you can modify your Operator's drone. The official description says those modifications augment abilities and can give advantages in later battles. This is the longer-term part of the loop, distinct from buying abilities and modifiers for a weapon during one run. The sources do not specify an upgrade menu, exact costs or a fixed order, so start by understanding the difference between the two progression layers rather than planning an unpublished build path.

First Mission: Your Focus

  1. 1

    Choose a weapon. This is the starting point for the build you will develop during the mission.

  2. 2

    Face the shared encounters. Fight enemies and bosses and take part in the announced challenges while looking for medal opportunities.

  3. 3

    Develop this run's build. Buy available abilities and modifiers and use found items where they make a useful combination with your weapon.

  4. 4

    Watch the competition. Your rivals face the same obstacles but pursue their own medals; use a Disruptor or a redirected boss attack when the situation favors interference.

  5. 5

    Read the result and prepare again. Medals determine the leaderboard and one Operator wins. After the match, consider drone modifications that can help in later battles.

These steps describe the announced gameplay loop, not unpublished buttons or matchmaking menus. If you are waiting to enter the game, the release date details distinguish the full PC release from the separate playtest waitlist; joining a waitlist is not the first gameplay step.
